Concentration of Higher Dimensional Entanglement:<? format?> Qutrits of Photon Orbital Angular Momentum
Physical review letters, 2003•APS
Enhancement of entanglement is necessary for most quantum communication protocols
many of which are defined in Hilbert spaces larger than 2. In this work we present the
experimental realization of entanglement concentration of orbital angular momentum
entangled photons. We investigate the specific case of three dimensions and the possibility
of generating different entangled states out of an initial state. The results presented here are
of importance for pure states as well as for mixed states.
